* Core - support for emergency URI,
What is this exactly? Any reference to ietf/itu specs?
I am not really sure myself as somebody else did the implementation. But
all the specs should be listed here:
http://www.openimscore.org/emergency . And even for us this is still
partly a branch with work in progress. The thing was that ser was even
crashing when it got some of these, so in any case, even if not used, it
would be a good patch.
I'll have to do a diff and find out what was exactly changes as there
were to many things in the last 3-4 years. And we probably have some
garbage through that. I'll send the patch after some cleanup.
IIRC openser/ser can not parse service URNs. Usually, if a UAC initiates
an emergency call, it looks like:
INVITE urn:service:sos SIP/2.0
Route: sip:uri-of-the-psap@example.com;lr
From: sip:user@domain.com;tag=123
To: urn:service:sos
...
Thus, the proxy does not even have to route based on the service URN,
but just on the pre-loaded route-set. Nevertheless, the proxy must not
crash or generate errors if the RURI and From/To URI does contain a
service URN. Actually From/To/RURI are allowed to contain any URIs (also
http URIs) - thus sr should supports parsing of these.
